Q: What is the procedure for a person who was baptized Macedonian
Orthodox and who now wants to be received into the Roman Catholic
Church? —
F.F., Toronto

A: In the vast majority of cases Orthodox Christians have been validly
baptized, confirmed and received the Eucharist from infancy, and thus do
not have to receive any of these sacraments.

Likewise, Catholic canon law allows a Catholic priest to administer the
sacraments of Eucharist, reconciliation and anointing to Orthodox
Christians if their own minister is unavailable or for other just
causes. (Most Orthodox Churches, however, do not approve of their
faithful availing of this possibility.)

For this reason Orthodox Christians intending to enter into full
communion with the Catholic Church would usually be able to participate
in the Church's sacramental life even before their formal incorporation,
either in the Latin rite or in an Eastern Catholic rite.

Prior to formal incorporation, they would still require a dispensation
from the bishop before entering into marriage and a man could not enter
into seminary formation. Nor could they receive any formal ministry.

The specific process for incorporating a baptized Eastern Christian is
covered above all in the Code of Canon Law of the Eastern Churches,
canons 35 and 896-901.

Canon 896 specifies that for those adult Christians (beyond 14 years)
"who ask of their own accord to enter into full communion with the
Catholic Church, whether as individuals or as groups, no burden is to be
imposed beyond what is necessary."

Canon 897 indicates that the Christian may be received "With only the
profession of faith after a doctrinal and spiritual preparation that is
suited to the person's condition."

With respect to individual laypersons the right to receive usually
pertains to the pastor although in some cases particular law might
reserve this admission to a higher authority (cf. Canon 898.3).

Canon 35, however, is important because it specifies that baptized
non-Catholics entering into full communion "should retain their own rite
and should observe it everywhere in the world as far as humanly
possible. Thus they are to be ascribed to the Church 'sui iuris' of the
same rite."

When the person wishes not only to become Catholic but to change to the
Latin rite, the same canon recognizes the right to approach the Holy See
(the Congregation for Eastern Churches) in special cases.

Therefore, in the case at hand, the simplest thing to do is to approach
the Eastern eparchy most closely resembling his original rite in order
to be admitted into the Catholic Church in accordance with the
dispositions of the pastor.

Once admitted, he should continue to practice the faith in the
corresponding Eastern rite. But he may also freely practice in the Latin
rite for a just cause, for example, if there were no churches of his own
rite within a reasonable distance.

In order to formally switch rites, he would need to recur to the Holy
See as mentioned above.

Follow-up: When an
Orthodox Joins the Catholic Church [10-30-2007]

Two readers, both expert canonists, sent in some clarifications that
expand on my earlier answer (Oct. 16) regarding how an Orthodox
Christian may enter the Catholic Church. I am very grateful and happily
share their wisdom with our readers.

I had suggested that the Orthodox Christian seek out the nearest Eastern
eparchy in order to make the profession of faith. A canonist informed me
that when this is not feasible, "The simplest thing to do, in the
likelihood that the proper Eastern Catholic Church 'sui iuris' is not
readily accessible, is for an Eastern Christian to make a profession of
faith before the local (usually Latin) Catholic pastor.

"The Eastern Christian recites the Nicene Creed and adds: 'I believe and
profess all that the holy Catholic Church believes, teaches, and
proclaims to be revealed by God' (RCIA, Appendix, 2, 15; USA, 474, 491).

"Ascription to the proper ritual Church 'sui iuris' is automatic but
needs to be recorded. Mentioning this in your column will be helpful in
reminding Latin priests (and priests of other Churches 'sui iuris') to
note it properly in the remarks of the baptismal registry (which usually
serves as the 'special book' referred to in RCIA, Appendix, 13; USA,
486)."

Regarding my statement that an Orthodox would need a dispensation in
order to enter into marriage, another reader clarified the terminology
and the ensuing legal consequences.

She wrote: "Please permit me to point out that it is incorrect to state
that an Orthodox requires a dispensation in order to marry in the
Catholic Church. Canon 1124 notes that marriage between a Catholic and a
baptized non-Catholic is 'prohibited' ('prohibitum est') without
'permission' ('licentia') of competent authority. Absent such
permission, the marriage is held to be illicit, rather than invalid.
This required permission is different from a dispensation, as a
dispensation is required to overcome an impediment which would affect
validity.

"The above pertains to all non-Catholic Christians, but current marriage
law is especially lenient, if you will, toward intermarriage with
Orthodox, with regard to canonical form. Ordinarily, all marriages are
required to follow the form delineated in Canon 1108.1, and a
dispensation is thus required if the couple wish to marry in the church
of the non-Catholic. Without this dispensation, the marriage would be
invalid due to lack of form. But the particular case of an Orthodox
Christian marrying a Catholic is specifically addressed further in Canon
1127.1: If the two were to marry in an Orthodox wedding ceremony, i.e.,
without following canonical form, the Church regards the marriage as
valid, although illicit."

Once more I express my gratitude for these observations which I am sure
will be as helpful to our readers as they have been to me.
